Basic Operating Information

Setting the Mode
The mode is set using the SET/RUN switch. Set this switch according to the operation to be performed.

ment of thresholds, power adjustment, zero reset, or key lock.
Key Operations
The operation keys are used to switch the displays and set detection conditions. The functions of the keys depend on the current
mode.
Key
RUN mode
UP key
Increases the threshold.
DOWN
key
Decreases the threshold.
Depends on the MODE key setting.

− Executes power tuning (default set-
− Executes a zero reset.
Time to Press Keys
If a specific time for pressing a key is not given in a procedure, press the key for approximately 1 second.
For example, if the procedure says "press the UP key," then press the UP key for approximately 1 second
and then release it.
Reading Displays
The information displayed on the main display and sub-display depends on the current mode.
For the default settings, the RUN mode displays will appear when the power supply is turned ON for the first time
